Answer: The rate of change of momentum of a body over time is directly proportional to the force applied and occurs in the same direction as the applied force.
We can write the law as:
Where F is a force, and P is the momentum.
Remember that the momentum is defined as the quantity of motion, such that:
P = M*V
Where M is the mass of the moving object and V is the velocity of the moving object.
Or we can write the second law as:
F = M*a
M = mass
a = acceleration

Answer:
600 cm
Step-by-step explanation:
Surface Area of a box: SA=2lw+2lh+2hw
Since a box has equal side lengths, <em>l </em>= 10, <em>w</em> = 10, and <em>h</em> = 10.
SA = 2(10)(10) + 2(10)(10) + 2(10)(10)
SA = 600cm
Answer:
Total number of quarters=10
Total number of nickels=19
Step-by-step explanation:
The expression for the total value of money you have is;
Quarters have a value of= $0.25
Nickels have a value of= $0.05
Total value=(value of quarters×number of quarters)+(value of nickels×number of nickels)
where;
Total value=$3.45
Value of a quarter=$0.25
number of quarters=x
Value of a nickel=0.05
number of nickels=y, but y=x+9
replacing;
3.45=(0.25×x)+0.05(x+9)
3.45=0.25 x+0.05 x+0.45
3.45=0.3 x+0.45
0.3 x=3.45-0.45
0.3 x=3
x=3/0.3
x=10
y=x+9=10+9=19
Total number of quarters=10
Total number of nickels=19
